ncaras.

To all whom it may concern:

.Be it'known that I, ALLEN J; GA RvnR, a citizen of the United States, and a resident of Clarkston, in the county of Asotin and State of Vfashington, have invented anew and Improved Apparatus for Treating Qin nabar Ore, of which the following is a full, clear, and exact descr ption. This lnvention relates to improvements in apparatus for treating cinnabar ore, and

more particularly to an improved construction of retort and condenser which cocper atein the recovery of mercury from the ore, andwhich, of course, may be utilized in con. nection with other metallurgical processes, an object of the invention being to provide improvements of the character stated, which facilitatethe recovery of themercury or other material and which economically performs the operation. I r

A further object is to provide improved means for heating the ore while in a finely divided state and while moving downwardly in-a retort over baflles which are heated and,

then conducting the'gas and fumes to an improved condenser where' the mercury is recovered and deposited in suitable settling tanks.

V A further object is to provide an improved construction of condenser which operates to subject the fumes to the action of water and permits the'mercur'y to escape as it is deposited and secures to a maximum extent the efficiency of the water in the condensing operation. p

With these and other objects in View the invention consists in certain novel features of construction, and combinations and arrangements of parts, as will be more fully hereinafter described and pointed out in the claims. p In the accompanying drawingse Figure 1 is a View partly in section and partly in elevation and more or less diagrammatic illustrating my improved apparatusi; p g Y i Fig. 2 is a fragmentary View in vertical section on the line 2-2 of Fig. 1;

Retort.

suitable material, theside walls of the re tort having grooves-1 therein-which grooves may, of course, be formed in the brick of; the wall and in these grooves a verticalseries' of staggered. inclined bafies 2 are located.

These battles are also preferably'of brick,

but of course, the invention is not limited to the particular material employed.

Av screw conveyer 8 located at the upper end of the retort is adapted-to feed fine particles ofore into the upper end of-the retort which particles move downward through the retort over the baffles by gravity and are discharged through an outlet 4 at the I have illustrated an bottom of the retort. ordinary gate 5 closing the outlet 4; but it is obvious that any form of outlet closure may v be provided and if desired, a closure in'the form of a screw propeller, such-asin-I dicated at 3. may be utilized to prevent the entrance of air at the bottom of theretort. j. T he bottom 6 of the retort is preferably inclined to the outlet 4- and under this bot-i tom 6 an air pipe 7 is located and discharges throughthe bottom upwardly into the re-- tort. The admission of air may be contr'olled'by a suitable cock 8 and the pipe may be arranged in the bottom in any desired.

wayto utilize the heat or" theore to heat'the pipe and the air passing therethrough so thatthe air entering the retort has thedesired temperature.

The baffles 2 are heated by means of burn ers 9. These burners are located in the walls of the retort and project through openings I 10 and are provided with suitable gates 11 which are slidablymounted .so as to allow f the entrance of airfor purposes of combustion to be regulated to suit conditions. As

these burners are preferably located under the bafiies 2, they heat the baflles to the neces-' sary degree so that the fine particles of ore are roasted as theypass downwardly through the retort, meeting the heated air ascending in the retort and generating gases or fumes, as will be read ly understood."

Condenser.

Thecondenser B is preferably of cylindrical form, horizontally positioned or at an incline, as desired, and mounted to revolve or rotate. VJhile,of course, the invention is not limited to any particularmeans for causing a rotary motion to be imparted to the condenser, I have illustrated a simple form of construction, which consists of the provision of circular "racks around the condenser and these racks are driven by pinions 18 on a shaft 14.

alternately arranged.

so that they project inwardly beyond'the inner edges of the 'staves 17 and provide, in effect, a circular series of inwardly pro ectmg blades or veins with grooves between them. The staves 17 maybe wider than the staves 16, as shown in Fig. 5, or any number of staves 17 may be located between the staves16 to bring about the desired internal construction. The purpose of the inwardly projecting blades or veins formed by the staves 16 is to exert an action on the water I in the condenser to move the water around inside the condenser and also to throw the same rearwardly toward the outlet 21.

' The condenser is provided at its ends with 1 heads 19 and 20 respectively and the inlet 18,

above referred to, is in the head 19 and is of general truncated conical form as shown. The head 20 is provided with a central outlet 21 for the excess of air and with a circular series of outlets'22 eommunicatin with the spaces between the staves 16 so as to allow the mercury to move outwardly from the condenser into a conical spout 23. The spout 23 discharges the 'mercury and the water over a trough 24- into the settling tank G anditis to be understood that I will provide a number of these'settling tanks C so that when one is filled, it can be replaced by an i empty tank and the filled tank set aside to allow the mercury to settle therein. The

* outlet spout 23 is partially inclos'ed by the lower end 'ofth'e vertical flue D, up which the gas and fumes, which escape from the condenser, are adapted to move.

This flue D is provided with a vertical series of staggered baffles 25 and these baffles are preferably of some material that will absorb water so that they will operate to recover any particles of mercury that may be containedtherein. V

A suitable pump 26 and pipe 27 supply water to the top of the flue D and this water passes downwardly over the baflles to keep them wet and counteractthe tendency of the mercury and the gas to escape. The gas 1 from the retort is conveyed to the condenser E by means of a pipe 28 having inlets 29 communicating with the upper portion of the retort and provided between its ends 7 with a fan or blower 30. A valve 31 in said pipe is adapted to be moved to control the draft therethrough and a water inlet'pipe 31. projects into the pipe 28 near its outlet end and discharges in the direction of the flow of the gas and passes with the gas into the condenser B. The inlet 18 0f the condenser B is of conicalshape so that the outi let end of the pipe 28 can be inclined downwardly to discharge the gas and Water into the bottom of the condenser and the pipecan be thus positioned regardless of the rotary motion of the condenser.

' The operation is as follows: fumes ascending in v the retort are drawn through the pipe 28 and discharged into the condenser E mixed with water, as above-ex-. plained, and in the condenser B the water 15 thrown upwardly and rearwardly by means of the staves 16 which form blades or veins.

The and The mercury passes out through the outlets 22 and the water through the outlet 21 into the spout 23 and from the latter flow into the acetylene tank 0. Such mercury as is recovored in the flue also descends into the tank C and the latter, afterit is filled, is

removed and the mercury allowed to settle so that it may be conveniently recovered.

While I have referred to my improved apparatus as one especially adapted for treating cinnabar ore to recover the mercury therein, it is apparent thatv the apparatus might be used for other metallurgical processes and hence, I do not wish to be limited to any particular process, but desireto cover the apparatus broadly for any use to which it maybe put. V

Various slight changes may be made in the general form and arrangement of partsdescribed without departing from the invention, and hence I do not limit myself to the precise details set forth but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of the appended claims Iclaim: v r i 1.
